Figure 4. Weaning of percutaneous ECMO.

ECMO = extracorporeal membrane oxygenation; MAP = mean arterial pressure; SvO₂ = mixed venous oxygen saturation; RV = right ventricular; S’ = tissue Doppler tricuspid lateral peak systolic velocity; CVP = central venous pressure; LVOT = left ventricular outflow tract; VTI = velocity time integral; LVEF = left ventricular ejection fraction; SFA = superficial femoral artery; PAOD = peripheral arterial occlusive disease; MCS = mechanical circulatory support

^*Low level of vasopressor/inotropes refers to norepinephrine ≤0.03 μg/min/kg and dobutamine ≤5 μg/min/kg.
